Masahiro Yamada 4c11edfcf7 Remove MODULE_ALIAS() calls that take undefined macro
These files do not define (USBHS_)DRIVER_NAME. Yet, they can be
successfully compiled because they are never built as a module by
anyone, i.e, the MODULE_ALIAS() calls are always no-op.

A problem showed up when a patch "moduleparam: Save information about
built-in modules in separate file" was applied. With this new feature,
MODULE_*() will be populated even if the callers are built-in.

To avoid the build errors, the lines referencing to the undefined
macro must be removed.

The complete fix is to remove all MODULE_* and #include <linux/module.h>
like many "make ... explicitly non-modular" commits did.

For now, I am touching only the offending lines.

Masahiro Yamada c69ef1c87b scripts/tags.sh: fix direct execution of scripts/tags.sh
I thought this script was run via "make tags" etc. but some people
run it directly.

Prior to commit a9a49c2ad9 ("kbuild: use $(srctree) instead of
KBUILD_SRC to check out-of-tree build"), in such a usecase, "tree"
was set empty since KBUILD_SRC is undefined. Now, "tree" is set to
"${srctree}/", which is evaluated to "/".

Fix it by taking into account the case where "srctree" is unset.

Daniel Dadap e46b94d228 scripts: override locale from environment when running recordmcount.pl
recordmcount.pl uses a set of regular expressions to parse the output of
objdump(1). However, if objdump(1) output is localized, it may not match
the regular expressions, thereby preventing recordmcount.pl from parsing
object files correctly.

In order to allow recordmcount.pl to function correctly regardless of the
current locale settings, set LANG=C when running objdump(1). LC_ALL is
already unset in the top-level Makefile, so it is not necessary to also
override that environment variable.

Wiebe, Wladislav (Nokia - DE/Ulm) 83da1bed86 modpost: make KBUILD_MODPOST_WARN also configurable for external modules
Commit ea837f1c05 ("kbuild: make modpost processing configurable")
was intended to give KBUILD_MODPOST_WARN flexibility to be configurable.
Right now KBUILD_MODPOST_WARN gets just ignored when KBUILD_EXTMOD is
set which happens per default when building modules out of the tree.

This change gives the opportunity to define module build behaving also
in case of out of tree builds and default will become exit on error.
Errors which can be detected by the build should be trapped out of the box
there, unless somebody wants to notice broken stuff later at runtime.

As this patch changes the default behaving from warning to error,
users can consider to fix it for external module builds by:
- providing module symbol table via KBUILD_EXTRA_SYMBOLS for
  modules which are dependent
- OR getting old behaving back by passing KBUILD_MODPOST_WARN to the build

Masahiro Yamada a788b2ed81 kbuild: check arch/$(SRCARCH)/include/generated before out-of-tree build
After cross-compiling the kernel, "make mrproper" should be executed
with the proper ARCH= option. Otherwise, stale objects will remain
under arch/$(SRCARCH)/.

One bad scenario is like this:

  $ make ARCH=arm defconfig all   # cross-compile the kernel for arm
  $ make mrproper                 # mrproper for host-arch (i.e. x86)
  $ make ARCH=arm O=build_dir defconfig all

If you miss ARCH= for mrproper and cross-compile the kernel with O=
and ARCH= options, Kbuild will happily start to build, but may fail
due to stale objects in the srctree.

If $(srctree)/arch/$(SRCARCH)/include/generated/ exists, let's stop
the out-of-tree build. To detect this, mrproper should clean only
arch/$(SRCARCH)/include/generated/.

Masahiro Yamada a9a49c2ad9 kbuild: use $(srctree) instead of KBUILD_SRC to check out-of-tree build
KBUILD_SRC was conventionally used for some different purposes:
 [1] To remember the source tree path
 [2] As a flag to check if sub-make is already done
 [3] As a flag to check if Kbuild runs out of tree

For [1], we do not need to remember it because the top Makefile
can compute it by $(realpath $(dir $(lastword $(MAKEFILE_LIST))))

[2] has been replaced with self-commenting 'sub_make_done'.

For [3], we can distinguish in-tree/out-of-tree by comparing
$(srctree) and '.'

This commit converts [3] to prepare for the KBUILD_SRC removal.

Masahiro Yamada e07cf4fd7d kbuild: mkmakefile: do not check the generated Makefile marker
This hunk was added to avoid accidental overwrite of the top Makefile
in case O= points to the top of the source tree.

As commit 4f1127e204 ("kbuild: fix infinite make recursion"),
it caused some troubles in the past because Kbuild assumes O=
as out-of-tree build, while it actually works in the source tree.

Now this works more properly; if O= points to the source directory,
it is handled as in-tree build. So, this sanity check is unneeded.

Masahiro Yamada 25b146c5b8 kbuild: allow Kbuild to start from any directory
Kbuild always runs in the top of the output directory.

If Make starts in the source directory with O=, it relocates the
working directory to the location specified by O=.

Also, users can start build from the output directory by using the
Makefile generated by scripts/mkmakefile.

With a little more effort, Kbuild will be able to start from any
directory path.

This commit allows to specify the source directory by using
the -f option.

For example, you can do:

  $ cd path/to/output/dir
  $ make -f path/to/source/dir/Makefile

Or, for the equivalent behavior, you can do:

  $ make O=path/to/output/dir -f path/to/source/dir/Makefile

KBUILD_SRC is now deprecated.

Manipulating $(MAKECMDGOALS) for sub-make seems odd to me.

[1] 'make O=foo sub-make' is turned into 'make O=foo', which builds
the default targets. It would make sense to terminate the build with:

  *** No rule to make target 'sub-make'.  Stop.

[2] 'make O=foo defconfig _all' is turned into 'make O=foo defconfig',

Rasmus Villemoes 9093464330 leds: trigger: netdev: use memcpy in device_name_store
If userspace doesn't end the input with a newline (which can easily
happen if the write happens from a C program that does write(fd,
iface, strlen(iface))), we may end up including garbage from a
previous, longer value in the device_name. For example

# cat device_name

# printf 'eth12' > device_name
# cat device_name
eth12
# printf 'eth3' > device_name
# cat device_name
eth32

I highly doubt anybody is relying on this behaviour, so switch to
simply copying the bytes (we've already checked that size is <
IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
still have to strip a trailing newline.

This is also preparation for future patches.

Linus Torvalds 32faca66bd Staging driver fixes for 5.1-rc3
Here are some small staging driver fixes for 5.1-rc3, and one driver
 removal.
 
 The biggest thing here is the removal of the mt7621-eth driver as a
 "real" network driver was merged in 5.1-rc1 for this hardware, so this
 old driver can now be removed.
 
 Other than that, there are just a number of small fixes, all resolving
 reported issues and some potential corner cases for error handling
 paths.
 
 All of these have been in linux-next with no reported issues.

Including:
 
 	- Fix a bug in the AMD IOMMU driver not handling exclusion ranges
 	  correctly. In fact the driver did not reserve these ranges for
 	  IOVA allocations, so that dma-handles could be allocated in an
 	  exclusion range, leading to data corruption. Exclusion ranges

Pull IOMMU fixes from Joerg Roedel:

 - Fix a bug in the AMD IOMMU driver not handling exclusion ranges
   correctly. In fact the driver did not reserve these ranges for IOVA
   allocations, so that dma-handles could be allocated in an exclusion
   range, leading to data corruption. Exclusion ranges have not been
   used by any firmware up to now, so this issue remained undiscovered
   for quite some time.

 - Fix wrong warning messages that the IOMMU core code prints when it
   tries to allocate the default domain for an iommu group and the
   driver does not support any of the default domain types (like Intel
   VT-d).

Linus Torvalds eed4897dfe Driver core patch for 5.1-rc3
Here is a single driver core patch for 5.1-rc3.
 
 After 5.1-rc1, all of the users of BUS_ATTR() are finally removed, so we
 can now drop this macro from include/linux/device.h so that no more new
 users will be created.
 
 This patch has been in linux-next for a while, with no reported issues.

Linus Torvalds 6f51092301 Char/Misc driver fixes for 5.1-rc3
Here are some binder, habanalabs, and vboxguest driver fixes for
 5.1-rc3.
 
 The Binder fixes resolve some reported issues found by testing, first by
 the selinux developers, and then earlier today by syzbot.
 
 The habanalabs fixes are all minor, resolving a number of tiny things.
 
 The vboxguest patches are a bit larger.  They resolve the fact that
 virtual box decided to change their api in their latest release in a way
 that broke the existing kernel code, despite saying that they were never
 going to do that.  So this is a bit of a "new feature", but is good to
 get merged so that 5.1 will work with the latest release.  The changes
 are not large and of course virtual box "swears" they will not break
 this again, but no one is holding their breath here.
 
 All of these have been in linux-next for a while with no reported
 issues.

 a fix for PCM is about the OOB access in PCM OSS plugins that has
 been for long time, but hasn't hit so often until now just because
 we allocated a large buffer via vmalloc(), and surfaced more often
 after switching to kvmalloc().  Another fix is for a long-standing
 PCM problem wrt racy PM resume.  Others are trivial nospec coverage
 and usual HD-audio quirks.
